nRf mesh

[smarter]

hello, 

we are interesting in some of your products and please answer my questions if you can. 

we are building a big parking place with private parking lots with individual gates. this parking gates have to receive and send bluetooth signals to operate. now we want to build a bluetooth mesh network so that parking can be operated by single desktop. so my questions are -

1) can nRF52840 Dongle give and receive bluetooth signals from any desktop? 

2) can nRF52840 DK receive and send bluetooth signals from/to nRF52840 Dongle?

3) if yes, can nRF52840 DK receive bluetooth information from Dongle and than send it to final device ( in our case to individual parking gate) and recive signal from final device and send it to dongle?

4) if yes, how many parking gates can nRF52840 DK work with simultaneously. 

5) what is the range of bluetooth signals for NRF52840 (how close parking ga gates has to be to work with DK)? 

6) can we use nRF Connect for Desktop software to build mesh and operate it. 

7) can nRF52840 DK or Dongle operate using wi-fi?

No. A mesh network doesn't work as a standard BLE extension. If you want to transmit some data this has to be done in your application.

Is there any device that can do that job? Work just as a BLE extension?

[awneil]

Yes, it can be done; eg,

https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/ble_sdk_app_rscs_relay.html

But remember that BLE is not really designed as a long-range network.

Maybe you should be considering a more appropriate radio technology?

Is this just to bridge the distance between a PC, perhaps in an office, and the mesh in the actual parking lot?

In that case, it might make more sense to have some other form of link from the PC to the lot, and this connects into the mesh at the lot ... ?

Again, unclear if this is a commercial development, or a student/hobby project - or what?

I will explain exactly what project I'm working on:

A building company has quite a big area in their complex. The area covers 430 parking gates that are intended to be used by those who live in the complex. There is a guard room next to this area. The guard needs to have access to all of these parking gates. (these parking gates use BLE) I have an android app, provided by the makers of the parking gates, that can add parking lots and lock/unlock them. The problem I have is to cover this big area (of 430 lots). If there is anything that can extend the range of my laptop or android device, without the need to write any application, my problem would be completely solved.

Thanks

So are you the "guard" ?

Surely, you should be talking to the gate manufacturer about this - as it must be a common requirement?
